Retbutiko is the online store of the Flandra Esperanto-Ligo (FEL), specializing in the sale of books, records, and educational materials related to Esperanto. The site offers several search tools, lists by author or translator, and a multilingual catalog. Quickly accessing the right section requires understanding the site’s architecture, its categories, and its ancillary pages, some of which remain less visible from the homepage.
Site Architecture of Retbutiko: What the Homepage Doesn’t Show
The homepage of Retbutiko displays two search tools. The first is a dropdown menu by predefined category (novels, new works, basic works). The second allows for free searching by keywords.
These two functions cover access to product sheets, but they do not provide a comprehensive view of all the pages on the site. Lists by author, translator, illustrator, collaborator, or critic are accessible via dedicated links, grouped under a “Lists by” section that does not always appear at first glance.
To obtain this overview, the complete sitemap of Retbutiko lists all the URLs of the site, allowing users to locate content pages or sections missing from the main navigation.

Category Search and Free Search on Retbutiko
The dropdown menu of categories serves as the first navigation filter. It classifies products by type (books, audio materials, philately, software) or by status (new releases, works recommended by William Auld for building a basic library in Esperanto).
The keyword search operates on a different principle: it queries the title, author, and description fields of each sheet. Combining the two tools significantly refines the results. For example, selecting the “novels” category and then entering a translator’s name allows for finding a specific edition without browsing the entire catalog.
Lists by Author, Translator, and Critic
Retbutiko offers dedicated lists accessible from the main page. Each list corresponds to an editorial role:
- Author and translator, to find all works by a given contributor in the Esperanto catalog
- Illustrator and collaborator, useful for illustrated editions or collective projects
- Critic, which links to published reviews on product sheets (the site displays nearly 4919 reviews in total)
These lists are sorted alphabetically and link directly to the corresponding sheets. They provide an efficient shortcut for visitors who know a specific name but not the title of a work.
Multilingual Navigation and Language Selection on the Site
Retbutiko is available in Esperanto, French, Dutch, English, and German. Language selection is done via flags located at the top of the page. Each language version maintains the same catalog structure, meaning that URLs change but the organization of categories remains identical.
This point has a practical consequence: a bookmark saved on the French version does not automatically redirect to the Esperanto version if the browser language changes. It is necessary to manually go back through the language selector or modify the URL prefix (/fr, /eo, /nl, /en, /de).
Legal Pages and GDPR Compliance
European online stores are required to comply with the information obligations set out in Article 13 of the GDPR: purposes of processing, legal basis, data retention period, and user rights. A complete sitemap should include direct access to these pages (privacy, terms of use, cookie management).
The analyzed competing pages do not describe this aspect of navigation. Field feedback varies on the visibility of this information in the Retbutiko interface, and access to the privacy policy is not always easily found from the main menu.

Payment Methods and Order Finalization on Retbutiko
The purchasing process on Retbutiko works by adding items to the cart: the user indicates a quantity in the dedicated column of each product sheet, then confirms everything via the shopping cart. The site offers multiple payment methods, accessible from a dedicated page.
For a store targeting French-speaking, Dutch-speaking, and English-speaking buyers across Europe, specialized guides published between 2024 and 2026 recommend a combination including SEPA transfers, credit cards, and at least one electronic wallet. The available data does not confirm which methods are currently active on Retbutiko, but the site mentions the existence of “various ways” to pay.
Access to Personal Data and Account Management
The site offers direct access to view and modify personal data recorded in the system. This link, sometimes difficult to locate, allows users to:
- Check the delivery address associated with the account
- Modify contact information without going through customer service
- View order history and shipping status
Using the sitemap remains the quickest way to locate this account management page, especially for occasional visitors who can no longer find the direct link.
Using the Sitemap to Locate Editorial Content
Beyond the commercial catalog, Retbutiko hosts editorial content related to the Esperanto-speaking community: announcements of congresses, educational resources, links to translations. These pages are not always referenced in the navigation menu, making them invisible to a visitor who only browses product categories.
The XML or HTML sitemap plays a catch-up role here. It lists every published URL, including those that do not appear in any menu. For users looking for specific content on Esperanto (literary prizes, detailed reviews, recommendation lists), this page becomes a more reliable entry point than the internal search.
Navigation on Retbutiko becomes smoother once the structural pages of the site are identified rather than limiting oneself to the two search bars on the homepage. The sitemap, contributor lists, and language selector form three shortcuts that cover the majority of user journeys on this Esperanto store.
